CLOSET DEVICE Filed March 31, 1943' Patented Apr. 9, 1946 CLOSET DEVICE Alfons Liiwenstein, Helsinki, Finland, assignor to Emil Fabritius, Helsinki, Finland Application March 31, 1943, Serial No. 481,234 In Sweden June 25, 1941 2 Claims.

This invention relates to sanitary closets, and particularly to portable sanitary closets in which a strong solution of caustic soda, for instance, is used in order to destroy the excrements so as to leave no odours. On account of the fact that the strong solutions, for instance of caustic soda, which are being used, have a very strong corroding effect on the skin, one is obliged, when using closets of the kind in question, to employ a receptacle placed above the surface of the liquid, on which receptacle the excrements drop down and which with the aid of an appropriate handling device can afterwards be lowered into the liquid and rinsed clean, and thereafter raised again above the liquid into position for use.

With closets of the above kind the receptacle, respectively its handling devices, have always been united with the closet basin itself, so that the cleansing of the closet has been diflicult and irksome, especially with portable closets. where sufllcient quantities of flushwater are not available.

The abovementioned drawback is removed by this invention in a simple manner, that is, the handling devices of the receptacle are attached to the closet lid-frame which is fastened to the closet basin in such a manner as to allow of its'easy removal, and it can, consequently, together with the frame and lid easily be lifted out of the bowl in order to be cleaned.

A simple example of closets executed according to the invention is schematically shown in the enclosed drawing, without the invention, however, being limited to the construction shown here.

The single figure of the drawing shows the closet bowl itself with its upper part tapering on in front in order to facilitate its emptying. At the back the bowl widens out slanting upwards to provide space for the guiding organs of the receptacle. 2 signifies the frame of the lid 3. Preferably not only the lid 3 but also the frame 2 are fastened by hinges to a narrow board 4, which is attached, for instance with wingnuts 5 or other easily removable fastening devices, to the brim flange above the backwards widening part of the bowl. In the example illustrated the receptacle 6, which has the form of a convex, backwards slanting tray, is at its two back corners fastened through two stays l to two tubular guide members 8 which can move up and down each along a guide rail ll fastened at its upper end to the frameboard 4. The guide members 8 are joined together by a cross-piece 9. A rod I0 is hinged to the cross-piece 9 and projects upwardly through an opening in the board 4 its upper end being hingedly connected to an angle-lever l2, I3 pivoted to the board 4, by the aid of which the the receptacle can thus be submerged into the liquid in the closet bowl or raised above the level of the liquid in position for use. M denotes an angular support, against which the lid leans when in an open position.

The device shown in the drawing can, naturally, be varied in many ways within the scope of the invention with regard to the form of the receptacle as well as to the type of operating mechanism.

I claim:

1. In a sanitary closet, the combination with a closet bowl and a narrow board secured to the rim of said bowl at the rear end thereof and covering the rearmost portion of said bowl, of a pair of rails secured to the underside of said board and projecting downwardly into said bowl. a cross piece slidable on said rails, a receiving tray secured to said cross piece, a rod hinged to said cross piece and projecting upwardly through a slot in said board, and a handle lever hinged to the upper side of said board and to the upper end of said rod for lifting and lowering said tray.

2. A sanitary closet, as claimed in claim 1, in which said slot extends lengthwise of said board, said rod being hinged to said cross piece and lever and the latter being hinged to said board for pivotal movements about axes extending at right angles to the longitudinal axis of said board.
